As a person who originally played Oblivion before Morrowind, I would much rather play Oblivion than Morrowind. I loved Oblivion, and as soon as I first started playing Morrowind, finding my first mudcrab, and killing it, the game just lost it's appeal as the prequel to my favorite game of all time. In Oblivion, the sound and music is better, the combat is better, you don't have to read as much to understand what the quests are or what people are saying, and the menu and upgrade system was much less complex (complex meaning spending hours thinking about what to level up in).
